Name/reputation still means a lot to some people, as does not learning yet another OS. Not everyone cares if something is FOSS or not. Different people have different leaning when it comes to this stuff, and that shouldn't be surprising.
I don't know QNX, never heard of them.
But the name and reputation of Blackberry are not things I would consider ... stellar or relevant...

Great, people on QNX can keep using it. A stagnating user base doesn't make for a good business.

No, but I would rather not enter into onerous licensing terms if better ones exist
